This data model will be reviewed and taken from the conceptual model to logical and physical model status.
Make sure you define the following:
1. Select one of the database management system (SQL Server, MYSQL), and identify the data types and sizes for all attributes.
2. Make sure all relationships have been addressed and corrected.
3. Review data model to make sure data model is in at least 3rd normal form (as defined by the normalization process).
Below is the link to the logical model that you can convert to a physical model. Please* using Microsoft Visio will be helpful for me as its what I have on my computer.
